Second in importance comes copra, which amounted to P35,740 in 1905 and P60,104 in 1906, or 12 and 21 per cent of total exports, respectively. The marked increase of this export in 1906 may be explained partly by increased production and partly by the general damage done to the trees in 1905 by locusts. Increase in the cultivation of coconut trees is not perceptible and can not account for the increase in exportation. Dried fish comes third in order, amounting to P15,786 in 1905 and P26,302 in 1906. This industry is capable of unlimited development. The fertility of the Sulu Sea is unusual and can hardly be surpassed. Nothing but enterprise and organized effort is needed to render this trade a source of enormous wealth to the country. The natives are exceedingly skillful in fishing, but lack ambition and initiative. The trade in fish is mostly in the hands of Chinese merchants. Fourth in importance comes hemp. Both in fiber and cordage its exports amounted to P11,140 in 1905 and P21,230 in 1906. Hemp culture has markedly improved during the last year, and the increased production is sufficient to explain the increase in exportation. Coconut trees and hemp grow splendidly on all the larger islands of the Archipelago, and their cultivation is capable of extensive development. Copal and gutta-percha are the products of Sulu, Basilan, and the Tawi-tawi Islands. Although sufficiently important in themselves, they sink into insignificance when compared with the four primary staple products and the immense possibilities that lie in the line of their development. The greater part of the trade of Jolo is handled by the Jolo Trading Company, the firm of Hernandez & Co., and the commercial houses of Chaun Lee and Ban Guan, all of which are controlled and managed by Chinese merchants. The following list compiled in the office of the Jolo Trading Company, for the Far Eastern Review, is a fair estimate of the prospective exports of the town for the coming two years:
